OYSTER BAY AS HOME OF MANY ALGAE

Algae is the group of eukaryotic organisms comprises of unicellular such as Chlorella and the diatoms as well as multicellulars such as the giant kelp, Most are autotrophic and lack stomata, xylem and phloem, rhizoids in nonvascular plants, and the roots, leaves, and other organs that are found in vascular plants. The largest and most complex marine algae are called seaweeds.

Algae include organisms having chlorophyll as their primary photosynthetic pigment but lacking a sterile covering of cells around their reproductive cells. Some scientists excludes prokaryotes and thus do not consider cyanobacteria (blue-green algae) as algae.

Examples of algae found at Oyster Bay rock shore includes; sargassum (sea weeds), vulva and green algae.

Green algae arethe group of unicellular organisms containing chlorophylls. Algae derives their energy from photosynthesis but some are heterotrophs (do not manufacture their own food) sometimes parasitic, relying entirely on external energy sources and have limited or no   mechanism of acquiring energy.

Sargassum is a genus of brown, family Sargassaceae and class Phaeophyceae (seaweed) in the order Fucales.

They inhabit shallow water and coral reefs. However, the genus is known for its planktonic (free-floating) species. While most species within the class Phaeophyceae are predominantly cold water organisms that benefit from nutrients upwelling, genus Sargassum appears to be an exception.
